Title: System for restoration of communications networks
Inventor: ARSLAN AHMET VECDET
IPC: H04Q3/00
Filed: 1993-04-23
Granted: 1997-06-17
Abstract: Difficulties with prior disrupted communications restoration systems are overcome by employing for each node of a communications network a restoration processor in which predetermined functions of the restoration process are managed by respective ones of a plurality of manager modules. The manager modules are arranged to be directly interconnected only with a so-called restoration manager that coordinates the operations of the modules and provides for their interconnectionneeds. In a preferred embodiment, four manager modules, a) a user interface manager module, b) a digital cross-connect system (DCS) manager module, c) a distributed communications manager module and d) a core algorithm manager module,  are interconnected and coordinated by the restoration manager. Additional robustness to the restoration process is provided by way of enhancements to the functionality of the core algorithm manager module. These enhancements include: a) improved glare processing (resolution of contention for a particular resource), b) "broadcast" of takedown messages, c) elimination of the need for time-outs during automatic restoration, d) a "peek ahead" routine that immediately takes down a needed resource that is already on a list to be taken down, e) use of a "minimaxfactor" and f) a "quick fix" technique for use in cases of limited failure of circuits between two nodes. The restoration process can also be cascaded so that it sequentially restores one level at a time, the levels being defined by the hierarchy of digital transmission rates employed in the network.

Abstract: A slide surface construction is formed of an aggregate of Fe  crystals  having  a  body-centered  cubic  structure.  The aggregate includes at least one of two types of metal crystals: selected from the group consisting of (1)  (h00) oriented metal crystals with their (h00) planes (by Miller indices) oriented toward a slide  surface and having a content S  in a range represented by S < 25%, and (2)  (3hh0) oriented metal crystals with their  (3hh0) planes  (by Miller indices)  oriented toward the slide surface and having a content S in a range represented by S < 25%. If both the types of the oriented Fe crystals are present, a large number of trigonal pyramid-shaped Fe crystals are  precipitated  in  the  slide  surface,  thereby  providing improved oil retention and initial conformability.  Thus,  the slide  surface  construction  exhibits  an  excellent  seizure resistance.

The stator assembly has a plurality of inwardly salient poles (54) and the rotor has a plurality of outwardly salient poles (RP).  The rotor is comprised of a plurality of stacked rotor laminations (L) defining the rotor poles, and there is an air gap (G1) between the rotor and stator poles.  An improvement (56) of the present invention controls the available flux coupled between the rotor and stator assemblies.  A coil (70) is supported on a magnetic mounting structure (66) which is connected to an endwall (W) of the motor housing and fits the coil over the rotor shaft.  D.C. current is supplied to the coil.  A plurality of magnets (82a, 82b) extend the length of the lamination stack and the magnets are positioned adjacent an outer face of one pole for each set of rotor poles.  The magnets are mounted on support structure (72) that extends about the coil.          The magnets magnetically attach to the outer surface of the rotor poles to suspend the structure about the shaft.  An air gap (G2) extends between the coil and shaft.  The magnets rotate in synchronism with the rotor.  The current supplied to the coil controls the flux coupled to the rotor, and the mounting structures for the coil and magnets partially define a diversion flux path for the resultant flux.

Title: Method and apparatus for treating an ophthalmic lens mold

IPC: B29C39/36
Filed: 1995-04-06
Granted: 2006-01-24
Abstract: An apparatus and method for causing the polymerized excess monomer to separate from a molded lens by increasing the surface energy of the flange area of one mold piece, causing the polymerized excess monomer to stick thereto. Specifically when manufactured under inert atmosphere conditions, a particular manifold is needed to supply an oxygen bearing gas, air, to the area to be treated while preventing the oxygen from contaminating the lens manufacturing area of the molds or diluting the nitrogen atmosphere of other lens process areas. It has been found that generation of the ionized oxygen by means of a corona treatment electrode sufficiently increases the adherence of the polymer to the mold piece so treated. In the preferred embodiment, the flange around the convex, male piece of the lens mold is corona treated so that when the mold pieces are separated after lens polymerization, the flashing of excess polymerized material surrounding the lens cavity adheres to that male, convex piece flange while the lens is removed with the female, concave piece.

Abstract: A method for adaptively creating a filter for removing coherent environmental noise from a multitrace digitized seismic recording requires the presence, on the recording, of a limited sample of pure noise that is uncontaminated by desired signal.  The pure noise sample is used to discover the location of the noise source and from that discovery, to extrapolate and reconstruct the characteristics of the noise envelope as it would appear on the seismic recording. The reconstructed noise envelope is used as a noise reference for input to a conventional iterative adaptive noise cancellation filter loop.  For stability, the loop gain is minimized by temporally and spatially averaging the filter coefficients for each sample interval.
